参考文档：
geckoview版本
引入文档（有坑 下面会给出正确引入方式）
官方示例代码1
官方示例代码2
参考了两位大神的博客和demo：
GeckoView js交互实现
geckoview-jsdemo
引入方式：
maven {
url "https://maven.mozilla.org/maven2/"}
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8}
implementation 'org.mozilla.geckoview:geckoview-arm64-v8a:111.0.20230309232128'
使用方式：
控件：
<?xml version="1.0" encoding="utf-8"?><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"><org.mozilla.geckoview.GeckoView
android:id="@+id/web_view"
android:layout_width="match_parent"
android:layout_height="match_parent"/><ProgressBar
android:id="@+id/web_progress"
style="@style/Web.ProgressBar.Horizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:visibility="visible"
